Environment-friendly and energy-saving water jet film removing machine

Abstract

An environment-friendly and energy-saving water jet film removing machine comprises a water storage tank, a high-pressure pump, a high-pressure water pipe and a spray nozzle. The high-pressure pump communicates with the spray nozzle through the high-pressure water pipe. The spray nozzle comprises, by weight, 50-80 parts of tungsten carbide, 2-16 parts of cobalt, 2-9 parts of ruthenium, 1-5 parts of nickel, 1-4 parts of titanium carbide, 1-4 parts of tantalum carbide, 0.5-3 parts of niobium carbide, 0.5-3 parts of chromium carbide, and 4-9 parts of vanadium carbide. The environment-friendly and energy-saving water jet film removing machine has the advantages of being better in compression resistance and abrasion resistance, longer in service life and capable of reducing the using cost.

Description

technical field [0001] The invention relates to a film removing device, in particular to an environment-friendly and energy-saving water knife film removing machine. Background technique [0002] The origin of high-pressure water jet technology can be traced back to the primary stage of low-pressure and high-flow water jet mining in the 1960s. Later, in the 1970s, water jet cutting technology was invented, that is, water was pressurized to 300-600MPa and made It is ejected from a nozzle with a diameter of 0.1-0.5 mm to form a high-speed water jet 1-3 times the supersonic speed. This high-speed water jet is used for cutting and becomes a water jet. Waterjet can perform surface cleaning, surface impact or cutting on products. Waterjet is favored because its cold cutting will not change the physical and chemical properties of materials. Now waterjet has been widely used in ceramics, stone, glass, metal, Composite materials and many other industries. Compared with traditional ...

Problems solved by technology

Wherein, during the working process of the water jet, the water flows out from the stable water source and enters the high-pressure pump, and the high-pressure pump pressurizes the water flow so that the water flow out of the high-pressure pump has a relatively high pressure (the specific pressure depends on the actual use of the water jet. Confirm), the high-pressure water flowing from the high-pressure pump flows through the high-pressure water pipe and is sprayed out through the nozzle. The sprayed water can spray the surface of the product, impact or cut the surface; however, since the water in the water jet is pressurized by the high-pressure pump Finally, the pressure is relatively high, which can reach 300-600MPa, and some are even higher, so that the water in the water jet will have a lot of pressure on the high-pressure water pipe and nozzle, which requires the high-pressure water pipe and nozzle to have a strong Compression resistance, wear resistance and hardness, so that the nozzle will not be damaged due to excessive water pressure; in the prior art, the commonly used nozzle material is cemented carbide, but because the commonly used cemented carbide has a single composition , the compression resistance, wear resistance and hardness are relatively limited, the nozzles are often worn, so that they are replaced frequently, the service life is not long, the cost is high, and it is very troublesome. The most important thing is that frequent replacement will also cause waste of resources. Conducive to environmental protection
